We just had sod installed at the office here at Crown Builders in Charlotte, NC. The landscaper told me to water each day for 15 minutes the first 10 days. From 10-21 days after install water every other day. After 3 weeks and beyond cut the lawn as needed. It should be fairly well rooted and can take normal wear and tear. Give it 1" of water each week. Apply balanced turf fertilizer 6 weeks after install.
